DEVICE FOR PURIFYING AIR CONTAINING DUST.

Specification of Letters Patent.

Application filed July 16, 1906. Serial No. 326,439.

To all whom it may concern:

Be it known that I, JOSEPH LEON PALOUS, a subject of the Emperor of Austria-Hungary, and a resident at Wilhelmstrasse 139, Berlin, Germany, have invented a new and useful Improved Device for Purifying Air Containing Dust, of which the following is a specification.

The present lnventionrelates to an improved device for purifying air containing dust, particularly in connection with the various methods of cleaning car ets and the like by means of air sucke or pressed through the same. The air charged with dust is moistened or wetted on entering the device in order to de 'osit the dust, and an important object of t e present invention is to automatically regulate the time and the amount of said moistening.

I attain the objects by the device illustrated in the accom anying drawing, in which said device is S own in vertical section.

The device consists of two reservoirs a and b, separated from one another, of which the one, a, serves as dust-chamber and the other, I), as water-reservoir.

c and d are the admission and outgoing air-pipes.

A pipe e having a right-angled socket f forming the continuation of the air-admission pi e c is in the chamber a, said pipe ebeing en arged at its lower end and closed bya valve-gat the junction of the narrow and broad parts. A pipe h, extending through the water-reservoir b, is partly inside t e pipe e and connected by holes '1', with the water in said reservoir and is closed at its lower end by a valve g The valves g and g are rigidly connected one with another. As illustrated, they consist of one piece with a common v'alve rod g.- A spring 7c presses both valves on their seats.

When the (purified) air is sucked through the pipe (1 from the chamber a, the reduced pressure thus arising opens the valve g. Therefore air containing dust can come throu h the pipe 0 and valve g into the lower end 0 the pipe e and from there into the dust-chamber. AS the valve 9 o ens, valve g opens also a corresponding istance, so that the air containing dust is moistened by the water flowing through the pipe h andthe dust is .for the most part deposited. Between the pipes e and d more known devices for purifying the air can be arrangedwhich,

for example, may be vertical or horizontalbut, however, do not form an essential part of this invention. An opening. Z normally closed by a cover permits the water to be released and the dust-chamber to be cleaned.

What I claim as my invention, and desire to Secure by Letters Patent, is

dust, comprising in combination an 'airchamber, a water-reservoir above the same, means in said air-chamber adapted to admit air, means in said air-chamber adapted to admit water, said means being adapted to be actuated automatically and simultaneously,
